Embodiment
Aforementioned and other technology contents, characteristics and effect about the present invention, will clearly present with reference in the graphic DETAILED DESCRIPTION OF THE PREFERRED in following cooperation.
Consult Fig. 2 and Fig. 3, one preferred embodiment of Bezier curve ultrasonic wave amplifier of the present invention comprises a main body 2, and loudspeaker 3 that are installed on this main body 2, these loudspeaker 3 are symmetrical structure around self axis, these loudspeaker 3 comprise that one side is installed in rear end face 31 and a front end face 32 of this main body 2, before these loudspeaker 3, rear end face 32,31 curve shape is shellfish (B é zier) curve now, wherein, the radius of these loudspeaker 3 rear end faces 31 is wide to be first radius 51, the radius of these loudspeaker 3 front end faces 32 is wide to be second radius 52, before these loudspeaker 3, rear end face 32,33 distance is an axial length L.
Consult Fig. 3 and Fig. 4, the manufacture method of Bezier curve ultrasonic wave amplifier of the present invention obtains best Bezier curve for utilizing the computer calculation, and Bezier curve is made this loudspeaker 3 according to this again, obtains best Bezier curve and comprises following steps:
At first, in step 41, first radius 51 of given operating frequency, these loudspeaker 3, second radius 52 and the axial length L, Bezier curve is by starting point 61, first, second and third control point 62,63,64 decision curved profiles, starting point 61 and the 3rd control point 64 are given by first and second radius 51,52 and the axial length L of these loudspeaker 3, and first and second control point 62,63 is a variable.
Successively, in step 42 to 45, set the generation number of first and second control point 62,63 set of variables, and many groups of first and second control points 62,63 variablees of given at random first generation, calculate each group pairing Bezier curve of variable and amplify usefulness.Determine next set of variables from generation to generation according to the best set of variables of amplifying usefulness of tool in each generation.At last, select pairing this group variable when amplifying usefulness the best, and corresponding Bezier curve.
The loudspeaker 3 of test Bezier curve gained, amplify usefulness be better than the dangling loudspeaker 3 of curve form, stairstepping amplifies usefulness and is better than Bezier curve, but, the loudspeaker 3 of stairstepping are when transmitting fluctuation, but can produce excessive stresses in inside configuration, and make this loudspeaker 3 structure steadinesss reduce, the stress that is produced according to the prepared loudspeaker 3 of Bezier curve is much smaller than the loudspeaker 3 of stairstepping.
What illustrate further is, in step 41 and 42, these loudspeaker 3 axial length L are 9.3cm, and these loudspeaker 3 first radiuses 51 are 1cm, and these loudspeaker 3 second radiuses 52 are 0.25cm, set Bezier curve from generation to generation number be 40 generations.
At first, in step 43 and 44, random number given first is totally 20 groups of first and second control point 62,63 variablees from generation to generation, and calculate each and organize pairing Bezier curve and amplify usefulness.
Wherein, calculate to amplify usefulness and comprise the resonance frequency that calculates each Bezier curve correspondence and the difference between operating frequency, and calculate the amplitude enlargement ratio at relative these rear end face 31 places, these loudspeaker 3 front end faces 32 places.What deserves to be explained is, the loudspeaker 3 of each bar Bezier curve have corresponding resonance frequency, frequency beyond resonance frequency can not have the amplification usefulness of resonance frequency through these loudspeaker 3 back amplitudes, only amplitude is enlarged into maximum on resonance frequency, and it is preceding, rear end face 32, the amplitude at 31 places is compared and is promptly got enlargement ratio, for example: foundation wherein made loudspeaker 3 its resonance frequencys of a Bezier curve is positioned at the 28.75kHz place, the amplitude at these loudspeaker 3 rear end face places 31 is 12.4 microns, the amplitude at these loudspeaker 3 front end faces 32 places is 130.2 microns, and enlargement ratio is 10.5 times.
Follow this step 45, in the middle of 20 groups of first generation, choose resonance frequency near operating frequency, and one group of the enlargement ratio maximum first and second control point 62,63, and organize first and second control point 62,63 given at random 20 group of second parameter group from generation to generation according to this, repeat abovementioned steps, select second best from generation to generation one group of first and second control point 62,63 and supply the 3rd from generation to generation, repeat abovementioned steps from generation to generation up to the 40.
This step 46 at last, in the 40 last generation, select resonance frequency near operating frequency, and one group of the enlargement ratio maximum first and second control point 62,63, be preferable Bezier curve, if will select better Bezier curve, by improving first and second given more groups at random control point 62,63 in each generation, and improve number from generation to generation, can obtain better Bezier curve.
In sum, the made loudspeaker 3 of Bezier curve in the sum total structural stability, amplify usefulness, the usefulness of making the difficulty each side is preferable, and preferable Bezier curve utilizes computer calculation help to obtain, at first given starting point 61 and the 3rd control point 64, given at random again first and second control point 62,63, filter out one group of best first and second control point 62,63 and promptly get best Bezier curve, so can reach purpose of the present invention really.
The above only is the preferred embodiments of the present invention, can not limit scope of the invention process with this, and promptly all simple equivalent of being done according to the present patent application claim and invention description content change and modify, and all still belong to the scope that patent of the present invention contains.
